is maintained in assembled condition without the use of nails, staples, or other fastening means.

A further object is to provide a. form of carton the parts of which are so related that the blank may be cut from sheets with a minimum of waste.

A further object is to provide a construction and relation of parts so that load bearing areas are reduced in size whereby compressional and torsional loads may be reduced to a minimum and great strength in the structure is possible with relatively light cardboard or similar material. I

Yet another object is to provide a construction of carton which can be formed from a cut blank in a minimum of time and with a minimum of effort, and which results in an exceedingly strong and self-bracing structure capable of carrying much heavier loads than is usually expected.

Further and more specific objects, features, and advantages will more clearly appear from a consideration of the detailed specification hereinafter set forth especially when taken in connection with the accompanying drawings which illustrate a present preferred form which the invention may assume and which form part of the specification.

In brief and general terms, the invention preferably includes a stamped blank having fold lines and adapted to be folded to form a carton which is held together without the use of staples or other fastening means. Generally speaking, it comprises side walls with an integrall connected intermediate-end wall and with integrally connected bottom sections adapted to be folded towards each other in an abutting planar relation with vertical integrally connected intermediate walls standing upwardly from the inner adjacent of said bottom sections. Preferably, the intermediate wall sections have handles projecting from their top edges and there are provided inintegral slotted cover sections to be folded over the top of the carton to close the same and receive the handle portions in the slots.

In another particular, the invention includes foot portions adapted to extend into the carton from the bottom of 'the end sections and above the bottom sections and spaced apart to receive snugly therebetween the intermediate wall sections.

Further the invention includes end flaps to be bent over inwardly from the top edges of the end wall sections and having notches to receive adja cent portions of the handles.

In further particular, the intermediate walls may be provided with cut out ears which may, when desired, be bent at right angles to their respective walls to divide up the interior of the carton into sections especially when the carton is to contain a series of separate containers.

A present preferred form which the invention may assume is illustrated in the drawings in which Fig. 1 is a perspective of the carton in assembled condition;

Fig. 2 is a perspective view with the carton partly assembled;

Fig. 3 is another perspective view showing the parts in the initial stage of assembly;

Fig. 4 is a horizontal cross section taken on the line 44 of Fig. 1; and

Fig. 5 is a plan view of the fiat blank from which the carton is formed by folding.

Referring to the blank shown in Fig. 5, it will be seen that we have two bottom portions l0 and I0, which are adapted to be folded into abutting Planar relation to form a complete bottom. To respective side edges of the bottom sections I0 and ID are connected intermediate wall members I2 and I2. To the respective opposite side edges of the bottom sections I0 and III are connected opposite side wall sections or members H and H. The respective intermediate wall members l2 and 12' are provided with ears l3 and I3 cut therefrom which ears may be, if desired, bent at right angles to the wall members l2 and 12', but in respective opposite directions as shown in Fig. 4. Along the top edge of the wall members l2 and H are formed handle portions it and II respectively having respective lips l5 and I 5' struck therefrom, and adapted to be bent up into the position shown in Fig. 1 to facilitate the carriage of the loaded carton.

To the top of the side wall members II and II are connected cover portions l6 and I6 respectively having respective slits I1 and I1 formed therein. These slits as shown in Fig. 1 are adapted to receive the handle portions I4 and it with the parts in assembled relation and the 3 oover members It and W are disposed over the top of the carton.

Intermediate the wall sections I and I I is disposed an end wall section II and at the opposite lateral edge of the side wall section II is connected another end section it. To the bottom edges of the end sections [8 and 18' are connected respectively pairs of feet I! and I9 disposed with a slight space between their adjacent edges. This space is sufficient, as shown in Fig. 2, to receive the abutting walls l2 and i2 between the pairs of feet I! and I8 when they are disposed flat along the bottom sections HI and III as shown.

To the top edges of the end sections II and I8 are connected end cover flaps 20 and 20' provided with notches 2| and 2| respectively. These notches are adapted to receive the upper portions of the wall sections I2 and I2 when in assembled condition as shown clearly in Fig. 2.

In Fig. 4, the carton is represented as containing a series of bottles or containers 22 as indicated by the dot and dash lines therein. Although of course, it is understood, that many other articles may be received in the carton and the nature of the articles to be received determines whether or not the ears l3 and [3' are to be operatively disposed as shown in Fig. 4. They are to be 50 disposed if you are going to use a series of separate containers, but if you wish to take advantage of merely two longitudinal chambers in the carton, then you will not use the ears. The assembly of the carton from the blank form shown in Fig. 5, is a verysimple matter of folding in successive steps and takes place as follows:

The initial step is shown particularly in Fig. 3 where the walls l2 and I2, H and II, have been bent up at right angles to the bottom walls or sections In and ID to which they are integrally related. It is seen also that adjacent ends of the walls II and H are integrally connected to the sides of end section i8. The walls I: and I! are then swung into abutting relation shown in Fig. 2, whereupon the legs iii are moved down from the bottom of section l8 to lie over the adjacent ends of the bottom sections l and ID. The other end wall It is then swung around at right angles to walls H and II and its feet l9 are moved down into a horizontal position over the adiacent ends with the bottom sections I0 and lb. The end flaps 20 and 20' are then bent inwardly into a horizontal plane and the notches 2| and 2| will receive the respective ends of the handles it and I4. After this, the cover portions l6 and [6' may be folded over into a horizontal plane overlapping each other with the handles I4 and i4 projecting through the slits l1 and I1 in said cover portions. At this moment, the carton is in the assembled condition shown in Fig. 1.

If the carton is to be carried, the lips I and ii are bent up out of the plane of the handles as shown in Fig. 1 to present a curved, smooth, wider surface to the palm of the person carrying the carton. If the carton is to be stowed away or shipped, the lips are not pulled out of the plane of the handles and the handle portions are respectively bent flat against the top of the carton in and II. The strength is also accentuated by the fact that the feet I! and I8 related to the end walls II and I8 embrace the bottoms of these intermediate walls and the end flaps 20 and II interlock with the handle portions I4 and H, in addition to the interlocking with said handle portions of the main cover portions 18 and It. The weight of the material in the carton whether separate containers or otherwise, will bear down upon these pairs of feet It and I! so as to maintain them in their interlocking position with the other parts.

It will be noted that in the sections it, It and II and II are intimately connected along lines of fold. It will be noted that sections l8, II, l0, and II are integrally connected along indicated lines of fold. It will be noted that sections 20, II and feet I! are integrally connected along indicated lines of fold. It will be noted that sections 20, I8 and feet iii are integrally connected along indicated lines of fold. It is also noted that sections I6, II, III and i2 are connected integrally along indicated fold lines.

While the invention has been described in detail and with respect to a preferred form shown in the drawings, it is not to be limited to such 1 details and forms since many changes and modiilcations may be made in the invention without departing from the spirit and scope of the invention in its broadest aspect. Hence it is intended to cover any and all forms and modifications of the invention which may come within the language or scope of any one or more of the appended claims.
